Abstract
PURPOSE Color-changeable chewing gums are used to evaluate masticatory performance, as measured by a colorimeter or visually based on a color scale. Although anyone can use a color scale, the evaluation accuracy depends on the evaluator. We develop an application that can determine the degree of color change in chewing gum using smartphone images, making color evaluation accurate and easy to measure. METHODS For the application, 60 chewed gum samples were prepared. Two shots were captured using two smartphone models. To create the application algorithm, a formula was developed to approximately map the color value from the smartphone images to the true value using a colorimeter. A basic validation was performed on 60 new samples covering a range of colors, followed by a field validation on 100 healthy dentate participants aged 20-39 years. RESULTS The intraclass correlation coefficient for two repeated shots had a high value ≥ 0.97 in the basic and field validations, confirming reliability. No significant differences were observed in the paired t-test and Wilcoxon signed-rank test, and a significant and strong correlation (correlation coefficient ≥ 0.92) was observed between the evaluation values using the colorimeter and the basic and field validations. Bland-Altman plots further confirmed the validity of the application. CONCLUSIONS A software application was developed to enable easy, quick, and accurate determination of the masticatory performance of a chewing gum from images taken using a smartphone with highly reliable and validated results.

J Am Med Dir Assoc 2023; 24:1855-1860.e1. [PMID: 37591488 DOI: 10.1016/j.jamda.2023.07.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 07/04/2023] [Accepted: 07/08/2023] [Indexed: 08/19/2023]
Abstract
OBJECTIVES In 2021, the Japanese government began operating a long-term care (LTC) database called the Long-Term Care Information System for Evidence (LIFE). However, its utility has not been verified. Regarding unplanned hospital visits of nursing home residents, one of the challenges in LTC is that poor oral health with undernutrition could indicate high-risk residents. Therefore, this study examined the association between poor oral health with undernutrition assessed using the LIFE data and unplanned hospital visits of nursing home residents. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS The participants were 237 residents aged ≥65 years in 4 nursing homes in Japan. The analyses included 1041 LIFE data entries repeatedly measured for the participants every month and unplanned hospital visit data during the observation period. METHODS The participants' LIFE and unplanned hospital visit data were obtained from the nursing home providers. Poor oral health was defined using oral items included in the LIFE data and body mass index. Using the LIFE data, the association between poor oral health and unplanned hospital visits within 1 month after LIFE assessment entries was analyzed. The odds ratios (ORs) and 95% CIs were calculated using a generalized linear mixed model. RESULTS In total, 59 of 1041 LIFE data (5.7%) entries were unplanned hospital visits within 1 month after LIFE assessment. Among patient characteristics, significant differences were noted in dementia diagnosis [OR (95% CI): 2.66 (1.26-5.63)], although no significant differences were observed in other characteristics. Multivariate analysis using participant identification as a random effect confirmed that poor oral health was associated with unplanned hospital visits within 1 month [adjusted OR (95% CI): 2.63 (1.05-6.61)]. CONCLUSIONS AND IMPLICATIONS Poor oral health assessed using the LIFE data could be used as an indicator to identify nursing home residents at high risk for unplanned hospital visits.

White matter abnormalities mediate the association between masticatory dysfunction and cognition among older adults. J Oral Rehabil 2023; 50:1422-1431. [PMID: 37710915 DOI: 10.1111/joor.13584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 06/30/2023] [Accepted: 08/17/2023] [Indexed: 09/16/2023]
Abstract
BACKGROUND Masticatory parameters, such as reduced number of teeth and posterior contacts, have been shown to be associated with reduced cognitive status. The underlying mechanisms that affect these associations, are however, not well understood. OBJECTIVES The study aims to investigate the association between masticatory dysfunction and cognition and explore the mediating effect of brain structure. METHODS In this cross-sectional study, 45 older adults with subjective masticatory dysfunction (mean age 72.3 ± 4.0 years) were included. Mini-Mental State Examination score <25, brain trauma, neurological disease, neurodegenerative disorders, depression or poor Swedish language skills were criteria for exclusion. Cognitive functions (executive function and episodic memory) and masticatory dysfunction defined by functional occluding status (FOS; the number of occluding units and number of remaining teeth) were analysed with partial correlation models. Structural magnetic resonance imaging was performed on 28 feasible participants. Multiple regression analyses were performed to evaluate the predictive value of brain structure and white matter hypointensities (WM-hypo) on cognitive functions. A mediation analysis was applied to assess significant predictor/s of the association between FOS and cognition. RESULTS Both episodic memory and executive functions were positively correlated with FOS. WM-hypo predicted cognitive status (executive function, p ≤ .01). WM-hypo mediated 66.6% (p = 0.06) of the association between FOS and executive functions. CONCLUSION Associations between FOS and cognitive functions are reported, where FOS, a potential modifiable risk factor, was related to both episodic memory and executive functions. The mediating effect of WM-hypo on the association between FOS and executive functions highlights the impact of the vascularisation of the brain on the link between mastication and cognition. The present study provides increased knowledge that bridges the gap between masticatory dysfunction and cognition.

Abstract
BACKGROUND Tooth loss is associated with reduced protein intake, which leads to sarcopenia and frailty in older adults. OBJECTIVE To evaluate the protective effect of dental prostheses on decreased protein intake in older adults with tooth loss. METHODS This cross-sectional study was based on a self-reported questionnaire targeting older adults. Data were obtained from the Iwanuma Survey of the Japan Gerontological Evaluation Study. We used % energy intake (%E) of total protein as the outcome and the use of dental prostheses and number of remaining teeth as explanatory variables. We estimated the controlled direct effects of tooth loss by fixing the use/non-use of dental prostheses based on a causal mediation analysis, including possible confounders. RESULTS Among 2095 participants, the mean age was 81.1 years (1SD = 5.1), and 43.9% were men. The average protein intake was 17.4%E (1SD = 3.4) of the total energy intake. Among participants with ≥20, 10-19 and 0-9 remaining teeth, the average protein intake was 17.7%E, 17.2%E/17.4%E and 17.0%E/15.4%E (with/without a dental prosthesis), respectively. Compared to participants with ≥20 remaining teeth, those with 10-19 remaining teeth without a dental prosthesis did not have a significantly different total protein intake (p > .05). Among those with 0-9 remaining teeth without a dental prosthesis, total protein intake was significantly low (-2.31%, p < .001); however, the use of dental prostheses mitigated the association by 79.4% (p < .001). CONCLUSION Our results suggest that prosthodontic treatment could contribute to maintaining protein intake in older adults with severe tooth loss.

Prevalence of frailty and its association with oral hypofunction in older adults: a gender perspective. BMC Oral Health 2023; 23:140. [PMID: 36899360 PMCID: PMC10007728 DOI: 10.1186/s12903-023-02824-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 02/20/2023] [Indexed: 03/12/2023] Open
Abstract
BACKGROUND Previous studies have indicated an association between oral hypofunction and frailty in community-dwelling older adults. However, this issue has not been evaluated in institutionalized older patients. We aimed to determine the prevalence of physical frailty in this particularly vulnerable group and evaluate its association with oral hypofunction, analyzing possible differences by gender. METHODS This cross-sectional study was conducted in private and public care homes in Guayaquil (Ecuador) from January 2018 until December 2019. Participants were classified as robust, pre-frail, and frail according to the Fried's frailty phenotype. Oral hypofunction was defined as the presence of at least three positive items in the following list: poor oral hygiene, oral dryness, reduced occlusal force, decreased masticatory function, and deterioration of swallowing function. The relationships between frailty and oral hypofunction were analyzed using logistic regression models for the whole sample and stratified by gender. Statistical analyses were performed using STATA 15.0 software (Stata Corp. LP, College Station, TX, USA). RESULTS Among the 589 participants analyzed (65% women), the median age was 72 years (interquartile range: 66-82). Pre-frailty and frailty were presented in 66.7% and 28.9% of them respectively. Weakness was the most frequent item (84.6%). There was a significant relationship between frailty and oral hypofunction in women. In the overall sample, the frequency of frailty was 2.06 times higher (95% CI 1.30-3.29) in patients with oral hypofunction, and this association was maintained in women (ORa: 2.18; 95% CI 1.21-3.94). Reduced occlusal force and decreased swallowing function were items significantly associated with the presence of frailty (ORa: 1.95; 95% CI 1.18-3.22 and ORa: 2.11; 95% CI 1.39-3.19, respectively). CONCLUSION The prevalence of frailty and pre-frailty was high among institutionalized older people and was associated with the presence of hypofunction, especially in women. Decreased swallowing function was the most strongly item associated with frailty.

Abstract
Background Masticatory ability is an essential factor for sustaining quality of life and social and systemic well-being, particularly in elderly. This study aimed to reveal the association between subjective masticatory difficulty and skeletal bone mineral density (BMD). Methods Data from the Korean National Health and Nutrition Examination Survey, which was conducted from 2008 to 2011 were analyzed. This study included 13,092 Koreans (5656 males, 7436 females) over 50 years of age. Masticatory difficulty was evaluated based on a self-reported questionnaire. Areal BMD of the total hip, femoral neck, and lumbar spine as well as lean body mass were determined using dual-energy X-ray absorptiometry. Data about the sociodemographic characteristics, physical activity, number of teeth present, sum of decayed, missing, and filled permanent teeth (DMFT) index and Community Periodontal Index (CPI) were collected. Multivariate logistic regression analysis was conducted to analyze associations between subjective masticatory difficulty and BMD, adjusting for the confounding covariates. Results Significant differences were observed in the areal BMD of the total hip, femoral neck, and lumbar spine as well as lean body mass accordance with the presence of subjective masticatory difficulty in both males and females. The number of teeth, DMFT, and CPI score did not show significant differences based on the presence of self-reported satisfaction of chewing performance in both males and females. Results from multivariate logistic regression demonstrated that the subjective masticatory difficulty showed significant interactions with skeletal BMD and the associations between masticatory satisfaction and BMD of the total hip and femoral neck were more prominent in females compared to those in males. Conclusions The skeletal BMD, particularly areal BMD of the femoral neck was significantly associated with subjective masticatory difficulty in elderly, especially in elder females.

Abstract
OBJECTIVES To assess the sociomedical and oral factors affecting masticatory performance in a community-dwelling older population. MATERIALS AND METHODS Community-dwelling persons over 60 years were investigated using medical and dental oral interviews, oral and denture examination (natural teeth, tooth mobility, number of occluding tooth pairs, and removable dentures' prevalence and quality), and evaluation of masticatory performance using a mixing ability test. RESULTS A total of 130 participants with a mean age of 73.9±8.5 years were recorded. Fifty-eight (44.6%) used various types of removable prostheses. Twenty were edentulous and used a pair of complete dentures. Univariate analyses revealed statistically significant associations (p≤0.05) between masticatory performance and aging, marital status, subjective chewing ability, use of removable dentures, use of various combinations of complete dentures, pain caused by maxillary denture, number of teeth, tooth mobility, posterior chewing pairs, all chewing contacts natural or prosthetic, retention of mandibular partial dentures, and dentures' occlusion. The multivariable quantile regression analysis revealed that fewer natural teeth (95% CI: -0.02-0.01, p<0.001), being edentulous and using a pair of complete dentures (95% CI: 0.09-0.35, p=0.001), and larger percentage of severely mobile teeth (95% CI: 0.07-0.82, p=0.020) were associated with lower masticatory performance. CONCLUSIONS Poor masticatory performance in older adults was associated with fewer teeth, being edentulous and using a pair of complete dentures, and increased prevalence of severe tooth mobility. CLINICAL RELEVANCE Retaining the natural dentition and preventing and treating periodontal disease are important measures to maintain masticatory performance in older adults.

Abstract
Background: Mini dental implant (MDI) overdenture rehabilitation for the edentulous maxilla is a valuable, less invasive and affordable treatment alternative for complete removable dentures (CRD). However, comparative quantification of masticatory performance in different oral conditions are scarce. Purpose: This study compares objective masticatory performance of dentate groups, maxillary CRD and MDI overdentures and subjective masticatory performance in maxillary CRD and MDI overdentures. Materials and Methods: Four groups were defined, age 20+ dentate dental students (DS), age 50+ complete dentate subjects (DP), age 50+ maxillary CRD or MDI overdentures/dentate mandible. Objective masticatory performance was evaluated by measuring circular Variance of Hue (VOH) or the mixture degree of two-color chewing gum (Hue-check View Gum® Test). Additionally, subjective masticatory comparison was investigated in the CRD and MDI groups, with a visual analogue scale (VAS) for different food consistencies and the Oral Health Related Quality of Life (OHRQL) OHIP-14 questionnaire. Results: The mean VOH was 0.11 (SD 0.50, range 0.05–0.27) for the dentate dental 20+ students, 0.13 (SD 0.08, range 0.03–0.31) for the 50+ dentate group (p = 0.774), 0.41 (SD 0.41, range 0.14–0.76) for the CRD group and 0.39 (SD 0.18, range 0.07–0.76) for the MDI group (p = 0.725). Based on the VAS scores, no improvement was found between the CRD and the MDI overdenture group (p > 0.050). The mean OHIP-14 total score was 12.10 (SD 15.87, range 0–56) for CRD, while the MDI group (p = 0.039) saw a significant improvement to 2.85 (SD 2.85, range 0–15). Conclusion: Comparable results in objective masticatory performance were registered in dentate 20+ and 50+ subjects with a remarkable inferior outcome for the CRD and MDI group. Compared to CRD, MDI overdentures revealed no substantial improvement in subjective and objective masticatory performance. However, for MDI a significant increase in OHRQL was apparent.

Abstract
OBJECTIVE To evaluate the association of masticatory function with prosthetic rehabilitation status and dental prosthesis functionality in nursing home residents. BACKGROUND Prosthetic rehabilitation status and dental prosthesis functionality may adversely affect mastication of older people, and this relationship is underestimated in nursing home residents. MATERIALS AND METHODS This cross-sectional study included 179 nursing home residents who used dental prostheses [mean (SD) age: 78.9 (9.0) years]. Masticatory function data were determined by assessing (a) masticatory performance using two-colour chewing gum, and (b) swallowing thresholds by counting the number of peanut chewing cycles. Older adults were categorised as: (1) using dental prostheses in both jaws (n = 100) and (2) partially dentate using removable partial dental prostheses (RPDPs) or complete dentures (CDs) in only one jaw (n = 41), or (3) edentulous using CD in only one jaw (n = 38). Stability, retention, occlusion, vertical dimension and defects were considered in assessing dental prosthesis functionality. RESULTS Greater variance of hue (VOH) of the chewing gum and lower swallowing thresholds (worse masticatory function) was associated with edentulous using CD in only one jaw. Older adults wearing dental prostheses with poor occlusion and vertical dimensions presented worse masticatory function. Dental prosthesis stability was associated with lower VOH values. Higher number of chewing cycles while eating peanuts was associated with non-broken dental prosthesis use. CONCLUSION Edentulous participants using CD in only one jaw and non-functional dental prosthesis use negatively affect the masticatory function of nursing home residents.
